[0002] During the construction process, it is necessary to frequently measure the construction coordinates, construction angles and heights of construction equipment within the construction environment. Among them, the measurement of construction coordinates mainly involves measuring the three-dimensional coordinates of the layout space points. In this construction method, the most commonly used instruments are total stations and GPS receivers. The main method for measuring construction angles is the theodolite, which can measure horizontal and vertical angles. In the measurement of the elevation of the construction environment and the building elevation, a level is mainly used for measurement.

[0003] During the use of the above-mentioned various construction instruments, due to the harsh outdoor environment, the above-mentioned instruments are often unusable. When it rains, due to the lack of corresponding cover, rainwater will corrode the instruments, and the lens part of the instrument will also become blurred due to the coverage of water droplets, which will make the measuring instrument unusable; when the direct angle of sunlight is close to the observation angle of the instrument, the light will interfere with the use of the instrument, making it impossible for the operator to observe. Therefore, the existing construction instruments are greatly affected by the external environment, which slows down the construction progress when the construction period is relatively tight, and urgently needs to be improved.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Please also refer to Figures 1 to 3 The light shield for a total station provided by the present invention is now described. The light shield for a total station includes a base 1 and a shielding mechanism 2, wherein the base 1 includes a bottom plate 11 and a clamping member 12, and the clamping member 12 can clamp the bottom plate 11 to the bracket of the total station; the shielding mechanism 2 includes a cover body 21, and the cover body 21 includes a flexible shielding plate 25 and two flexible fan-shaped plates 26. The two flexible fan-shaped plates 26 are arranged at intervals along a first horizontal direction, and the central angles of the flexible fan-shaped plates 26 are connected to the bottom plate 11. The side edges of the flexible shielding plate 25 are integrally connected to the arc edges of the tops of the two flexible fan-shaped plates 26. One of the busbar edges of the flexible fan-shaped plates 26 is coaxially connected to a first support rod 211, and the other busbar edge is connected to a second support rod 212. The first support rod 211 and the second support rod 212 can converge around the center of the flexible fan-shaped plates.

[0029] Compared with the prior art, this embodiment can control the retraction and extension of the cover body 21 by the mutual convergence and expansion of the two support rods. In the expanded state, the cover body 21 can be placed above the detection instrument (such as a total station or theodolite, etc.), solving the technical problem that the detection instrument cannot be used due to bad external weather; in addition, this embodiment can also remove the cover body 21 from the bracket through the snap-fit ​​part 12, and can reduce the storage space required for the shielding mechanism 2 by folding the cover body 21, so that the shielding mechanism 2 in this embodiment is easier to store; in addition to the above-mentioned beneficial effects, the cover body 21 in this embodiment has a simple structure, and the weight of the entire cover body 21 is also lighter than the existing metal sunshade and plastic sunshade, and it is convenient to install and carry.

[0030] Optionally, the flexible fan-shaped plate and the flexible fan-shaped plate 26 in the above embodiment can be made of polyvinyl chloride. To facilitate the folding of the cover body 21, a preferred embodiment is proposed. Specifically, a plurality of first folds are provided on the polyvinyl chloride flexible fan-shaped plate 26, and a plurality of second folds are provided on the flexible shielding plate 25. The fold lines of each first fold are evenly spaced, and each first fold coincides with a radial line of the flexible fan-shaped plate 26. The fold lines of each second fold are parallel to the first horizontal direction. In this way, the flexible fan-shaped plate 26 in this embodiment can bend at the location where the first fold is provided and extend according to the first fold. Similarly, the flexible shielding plate 25 can bend and expand according to the second fold, making the expansion and contraction process of the entire cover body 21 more controllable.

[0031] Based on the above embodiments, a feasible implementation method is proposed. Specifically, the clamping member 12 includes a first clamping plate 121 and a first bolt member 122. The clamping plate 121 is arranged below the base plate 11 and can be close to the base plate 11 in the up and down directions. The axial direction of the first bolt member 122 is parallel to the up and down directions and is used to connect the base plate 11 and the clamping plate 121. With such an arrangement, this embodiment can be installed at the connection between the detection instrument and the bracket by pressing the clamping plate 121 against the base plate 11, so that the connection between the cover body 21 and the bracket in this embodiment is more secure.

[0032] As a feasible embodiment, the shielding mechanism 2 also includes a second bolt member 22, a first locking plate 23 and a second locking plate 24. The second bolt member 22 coaxially penetrates the first locking plate 23 and the second locking plate 24 along the first horizontal direction, and can make the first locking plate 23 and the second locking plate 24 tightly attached. The first locking plate 23 is integrally connected to the bottom end of the first support rod 211, and the second locking plate 24 is integrally connected to the bottom end of the second support rod 212. The corresponding inner sides of the first locking plate 23 and the second locking plate 24 are respectively formed with a first locking ridge 231 and a second locking ridge 241. There are multiple first locking ridges 231 and second locking ridges 241, and each first locking ridge 231 and each second locking ridge 241 are radially and evenly arranged around the second bolt member 22. Each first locking ridge 231 and each second locking ridge 241 are alternately inserted. In this embodiment, by tightening the second bolt member 22, the first locking plate 23 and the second locking plate 24 fit tightly together, and the locking edges on the two locking plates engage with each other, thereby locking the opening angles of the first support rod 211 and the second support rod 212 respectively connected to the two locking plates, thereby preventing the two support rods from swinging during the transfer of the detection instrument.

[0033] Of course, from the perspective of manufacturing cost, it is also possible to set up only one locking plate, which can be integrally connected to the first support rod 211. A plurality of positioning grooves can be set on the side of the locking plate facing the second support rod 212 to lock the expansion angle between the second support rod 212 and the first support rod 211 according to actual conditions.

[0034] As a feasible embodiment, the cover body 21 further includes a first connecting rod 213 and a second connecting rod 214. The axes of the first connecting rod 213 and the second connecting rod 214 are both parallel to the first horizontal direction. The two ends of the first connecting rod 213 are respectively connected to the top ends of the two first support rods 211, and the two ends of the second connecting rod 214 are respectively connected to the top ends of the two second support rods 212. In this embodiment, the first connecting rod 213 and the second connecting rod 214 can form a frame structure with the first support rods 211 and the second support rods 212, respectively, to enhance the structural strength of the entire cover body 21 and prevent the cover body 21 from being damaged by wind and other factors. Furthermore, based on the above embodiment, a first diagonal brace is provided between the first connecting rod 213 and the first support rod 211, and a second diagonal brace is provided between the second connecting rod 214 and the second support rod 212 to further enhance the connection rigidity between the support rods and the connecting rods, making the total station light shield of this embodiment suitable for use in various harsh environments.

[0035] As a feasible embodiment, along the first horizontal direction, two flanges 111 are respectively provided on both sides of the base plate 11, both of which are bent upward. The second locking plate 24 and the first locking plate 23 are stacked on one side of the flange 111 in the direction away from the base plate 11, and the second bolt member 22 passes through the first locking plate 23, the second locking plate 24 and the flange 111 along its own axial direction. With such an arrangement, this embodiment can install the first support rod 211 and the second support rod 212 mentioned above through the flange 111 provided on the base plate 11, thereby forming a stable connection between the cover body 21 and the base plate 11; more preferably, based on the above embodiment, the first locking plate 23 or the second locking plate 24 is connected to the flange 111, so that the first support rod 211 or the second support rod 212 serves as a fixed rod, and the other serves as a movable rod, so that the retraction and extension of the cover body 21 is easier to operate.

[0036] Based on the same inventive concept, the present invention also proposes a construction detection device, which includes the light shield for the total station mentioned above.

[0037] Compared with the prior art, the construction inspection equipment in this embodiment has all the benefits of the above-mentioned total station light shield, which will not be repeated here.
